This has happened many times: British spelling or pronunciation deviates in modern times -- often due to classist tensions special to England -- but then ultimately the British incorrectly suppose the American way is the "ahistorical" one. Another famous one is "solder". Until about 1920, the British universally pronounced it like the Americans did (derived from the French "souder"). Then the British slowly revised their pronunciation.
